NCIS Casts 24 Vet Sarah Clarke as Special Agent Tess Monroe

Former 24 traitor Sarah Clarke is joining NCIS in the potentially series-regular role of FBI Special Agent Tess Monroe, TVLine has learned.

As TVLine first teased back in January, Tess is a quick-witted, tough and shrewd agent who recently transferred to D.C. from New York City. A multiple divorcée who’s as sexy as she is strong, Tess has no kids so she views her fellow agents as family. Beneath a no-nonsense shell, Tess has a big heart. She believes in honor and justice and doing what’s right. And she’ll fight to protect those values, and her team, with fierce determination and a tinge of sarcasm along the way.

Clarke, who also played a federal agent on Covert Affairs, will guest-star in this season’s final two episodes and has an option to return as a full-fledged regular in Season 14.

“We feel so fortunate to have Sarah Clarke joining us to play Tess,” said NCIS EP/Showrunner Gary Glasberg in a statement. “I’ve been a fan of her’s going back to 24 and, more recently, Bosch. She’s a gifted actress, a total pro, and we can’t wait to introduce her to our NCIS family and have some fun.”
